Summary

This book presents edited key papers from the International Symposium on Grassland Ecophysiology and Grazing Ecology held in Curtiba, Brazil in August 1999. It considers how plants within grasslands respond to and are adapted to grazing animals. Contributors are leading authorities from North and South America, Europe and Australasia.
